No. 7,151,219, which is a Continuation-In-Part of U.S. patent application Ser. No. 11/070,344, filed Mar. 2, 2005 and now U.S. Pat. No. 6,965,078, which is a Continuation-In-Part of U.S. patent application Ser. No. 11/009,116 filed Dec. 10, 2004 and now U.S. Pat. No. 7,005,578, which is a Continuation-In-Part of U.S. patent application Ser. No. 10/863,942 filed Jun. 9, 2004 and now U.S. Pat. No. 6,956,171, all of which are commonly owned by the assignee of the present invention and the entire contents of which are incorporated herein by reference.
This invention relates to assemblies for the mounting of electrical devices and specifically to a recessed electrical box assembly that includes an electrical box portion and a trim plate for recessing and protecting an electrical device therein.
Recessed electrical boxes for retrofitting on finished walls or for use in new construction were disclosed in U.S. Pat. Nos. 6,965,078, 6,956,171, 7,005,578, 7,045,713, 7,064,271, 7,115,820, and 7,151,820, 7,166,801 and in co-pending U.S. application Ser. No. 11/655,299, all of which are commonly owned by the assignee of the present invention and the entire contents of which are incorporated herein by reference.
The recessed electrical boxes disclosed in the aforementioned patents and applications comprised an electrical box having an inner enclosure for housing an electrical device and an outer enclosure for recessing the inner enclosure well within a wall. The recessed electrical box including the inner enclosure and outer enclosure were either integrally formed in one piece or provided in two pieces each formed of the same material of construction.
Although a recessed electrical box of the type described in the aforementioned disclosures provided an adequate means for recessing an electrical device substantially within the wall of a structure, they were directed primarily to recessing a single high voltage electrical device. Although the aforementioned patents and patent applications provide an apparatus for recessing a high voltage electrical device on the exterior of a structure, there is also a need for recessing multiple electrical devices, including both high and low voltage components, on the wall of a structure.
Accordingly, the present invention provides a two-gang recessed electrical box assembly that includes a first portion that comprises an electrical box for recessing two electrical components within a wall. The two-gang recessed electrical box assembly can accommodate two high voltage components, two low voltage components, or one high voltage component and one low voltage component. A second portion of the recessed assembly includes a trim plate for covering the electrical box and a portion of the interior wall surrounding the box to obscure that portion of the wall surrounding the electrical box. The two-gang recessed electrical box assembly provides an outer enclosed area for shielding and protecting the plug ends of electrical cords or similar cables connected to the electrical components housing in the assembly.
The invention is a two-gang recessed electrical box assembly for recessing two electrical components within a wall. Either high or low voltage components can be installed within the assembly. The recessed electrical box assembly includes an electrical box and a trim plate. The electrical box includes sidewalls and a back wall defining an enclosure therein. Two high voltage components or two low voltage components can be installed within the enclosure, or an optional voltage separator can be installed to divide the enclosure and to enable the mounting of both a high voltage and low voltage component in the resultant subdivided enclosures. The trim plate includes a laterally extending flange and a rearward-extending collar that is received within the sidewalls of the electrical box. Alignment tabs are provided on the sidewalls of the electrical box to enable easy alignment against a stud in either a new work or retrofit situation. Nailers are provided on the outer sidewalls of the electrical box for securing the two-gang electrical box assembly to a stud or similar support. The nailers are angled away from the sidewalls and toward the front of the electrical box and include captive fasteners to simplify the installation of the recessed electrical box assembly to a wall.
A first object of the two-gang recessed electrical box assembly of the present invention is to provide a recessed electrical box that can accommodate both high and low voltage electrical components within the same assembly.
A second object of the two-gang recessed electrical box assembly of the present invention is to provide an electrical box assembly that positions one or more electrical devices behind the wall surface, thereby recessing the electrical devices and enabling cabinets, wall clocks, appliances, and the like to be positioned close to the wall without interference or obstruction from the electrical device.
A third object is to provide a two-gang recessed electrical box assembly that shields all of the installed electrical devices and any electrical cords plugged therein from splashing water, grease, impacts from vacuum cleaners, or other household hazards.
A further object is to provide a recessed electrical box assembly that provides a recessed area or cavity within the wall to hold the plug ends of electrical cords while they are in use, thereby recessing the plug ends away from the wall and from interference with the appliance or device they are providing electrical feed to.
Another object of the present invention is to provide a two-piece recessed electrical box assembly that includes nailers with captive fasteners for easing the installation task. The captive fasteners are angled outwards with respect to the sidewalls of the box and angled toward the front of the box to make them more easily accessible to an installer in a retrofit situation.
These and other objects and advantages of the present invention will be better understood by reading the following description along with reference to the drawings.
